Quit-smoking instrument using theory of planned behavior in nursing

Abstract

Tobacco in cigarettes is a legal drug that can cause death for those who consume it. Until now smoking can cause various complications that have an impact on health such as cancer and heart disease. Behavioral theory such as TPB (Theory of Planned Behavior) is a behavior-based nursing theory that allows behavior change to minimize the impact of smoking. And until now there is no standardized instrument that measures a person's smoking behavior using the TPB application. Therefore, this study will develop a TPB model of smoking behavior instrument. This research is a non-experimental cross sectional study through validity and reliability tests carried out in 4 stages: literature review, instrument development, Content Validity Index and Internal consistency reliability. The reliability test was carried out on 93 respondents who were taken by accidental sampling with the criteria of male smokers aged 15 to 60 years, no history of disease due to smoking, willing to be participants and able to read and write. Internal consistency reliability analysis through Cronbach's Alpha value. The results of the study showed that as many as 40 instrument items had been developed, with an average I-CVI value of 4 experts being 0.75-1.0. While the average Cronbach's Alpha value reached 0.870. The smoking behavior instrument that measures the TPB component that has been developed is valid and reliable.
